Weight loss injections are FDA-approved prescription medications administered subcutaneously once weekly to support clinically significant weight loss in adults with obesity or weight-related conditions. In 2026, the leading options are GLP-1 receptor agonists (Wegovy, Saxenda) and the dual GIP/GLP-1 agonist Zepbound, which curb appetite, slow gastric emptying, and produce 15-22% body weight reduction in trials. Most patients access them through telehealth providers, with prices ranging from $300 to $1,400 per month depending on insurance, brand, and compounded availability.
Weight loss injections have revolutionized the medical weight loss industry, offering unprecedented results for people struggling with obesity and weight management. These FDA-approved medications, particularly GLP-1 receptor agonists, have transformed how we approach weight loss by targeting the body’s natural hunger and satiety mechanisms.
What are Weight Loss Injections?
Weight loss injections are FDA-approved medications administered via subcutaneous injection to help with weight management. These medications work by targeting specific pathways in the body that control appetite, metabolism, and food intake. Unlike traditional diet pills, these injections provide sustained effects and are typically administered once weekly.
